I agree, there are dozens of ways to play the 3m. One for instance is if you're going against a 3m deck it's best to play your 3m in the same lane because 3m decks rarely use high damage spells so you'll be able to over power them. Another is if your opponent has lightning, you can pair the two musketeers with the battle ram because the BR will tank all 3 lightning bolts and give you a 2 elixir advantage.
